Research On Energy Balance Routing Of Aircraft Ad Hoc Network Based On Link Prediction

With the rapid development of wireless communication technology,flying ad hoc network had been became a new research hotspot.In the harsh environment,the highspeed mobile nodes and the high dynamic network topology posed new challenges to the routing technology of FANET.Aiming at the shortcomings of the existing FANET routing protocols in ensuring the path stability and node energy balance,this paper made an in-depth study of the commonly used AODV routing protocol,and found that there were some shortcomings when it was used in FANET.It was mainly reflected in that the residual energy of nodes was not fully considered in the process of routing path establishment,and some nodes were overused.After route discovery,it would continue to be used without releasing until the node moved or died.Broadcasting hello packets at fixed intervals for routing maintenance brought a certain burden to the channel.So that,this research proposed an energy-balanced routing algorithm LPEB?A.By constructing the aircraft motion information model,the link lifetime was calculated,and the interruption prediction was based on it.Firstly,in the aspect of energy balance,the residual energy of nodes was calculated and quantified in the process of route discovery,so as to build a high stability spatial route with energy balance.Secondly,in the process of information transmission,routing decisions were made,and nodes with high path scores were selected for information transmission.Finally,in the link maintenance phase,a HELLO packet information transmission mechanism based on genetic algorithm was proposed.The HELLO interval of LPEB?A was optimized,so that the network nodes can choose the appropriate time interval for HELLO packet transmission,and better adapt to the dynamic network structure.Further realize the energy balance of network nodes.At last,the simulation results showed that compared with the existing related routing algorithms,the energy-balanced routing algorithm proposed in this research based on FANET link prediction can effectively reduce network energy consumption,save network overhead,enhance link stability,and increase the data packet delivery rate.
